A 14-month MVNO build, replaced with three weeks of integration.
Aviato is a European online travel platform serving 12M bookings a month across 38 countries. Their team had spent six months scoping a custom MVNO build to bundle roaming with bookings. Next replaced that roadmap with a sandbox key on day one.
When Aviato customers booked an international trip, the conversation ended at checkout. The traveler stepped onto the plane and into someone else's customer relationship — the airport SIM kiosk, the airline's WiFi vendor, the local prepaid shop. Aviato had no presence in the moment that mattered most: the moment the traveler arrived and needed data.
Internal scoping for a custom MVNO build returned a 14-month timeline, €4.2M of capex, and a regulatory checklist spanning seven jurisdictions. The product team's view: 'We'd be building telecom infrastructure to sell SIMs to people who already have phones.' The CFO's view: 'We'd be building it twice — once for Europe, once for everywhere else.'
What they actually needed was simple: a single API call at booking confirmation that provisioned an eSIM tied to the trip, activated at first foreign network attach, and expired on the return date. What they were quoted was a 14-month telecom project.
Aviato's engineering team had sandbox keys in 60 seconds and a working prototype tied to their booking webhook in 48 hours. The integration uses Next OneSIM's provision-on-confirm pattern: when a booking flips to confirmed, the API creates an eSIM with the trip's destination and dates baked into the plan metadata.
The QR code lands in the booking confirmation email. The traveler installs the eSIM at home. When the device hits a foreign network at the destination, OneConnect fires a webhook back to Aviato's CRM, triggering an in-app welcome notification with local recommendations and an upgrade prompt.
On the back-end, OneConnect streams network events into Aviato's data warehouse — activation, usage milestones, low-balance alerts, expiry. The same pipeline that drives marketing automation now drives connectivity engagement. One API to provision, one webhook to engage, one trip to bill against.
Aviato shipped to production three weeks after sandbox start. Within 90 days of launch, the connectivity bundle had become their highest-margin ancillary product — outperforming both travel insurance and seat upgrades on attach rate.
We turned roaming from a customer complaint into our highest-margin ancillary. The integration took two weeks. The revenue impact showed up in the first month.
Sandbox keys in 60 seconds. Production in days. Ship before the next quarterly review.
